To all whgm 'it may con/:em:

Be it known that I, PASQUALE DANGnLo, a subject of the King of Italy,residing at Newark, in the county 'of Essex and State of New Jersey,have invented certain new and useful Improvementsin Padlocks, and I dohereby declare the following to be a full, clear, and exact descriptionoi the invention, such as will enable others skilled in the art to whichit appertains to make and use the same, reference being had to theaccompanying drawings, and to -igures of reference marked thereon, whichform a part of this specification.

This invention relates to a lock that is particularly designed for apad-lock, but is adapted for other uses, the lock being of the classthat has a shackle arranged to slide into a casing to be locked therein,and to slide from the casing and then'be swung to have one end clear thecasing. The present lock is designed to snap shut, when the shackle isslid into the casing, but provides a means for locking the shackle bymeans of a key besides the automatic means, the key locked portion ofthe device preventing the unlocking by 'means of the springactuatedlocking means, so that the key locked portion must be unlocked rst.

The .device provides'a means for allowing longitudinal action of a keyused in conjunction with the lock,

so that the key canoperate in different planes, in a` par-` ticularsequence, to provide for the unlocking of different elements in theirturn to complte the unlocking of the device. i

The invention is illustrated in the accompanying drawing', in which iFigure l is a face view of the lock with one side thereof removed, withthe lock after it is shut, show.-

A completely locked. Fig. 3 is across-section on line 3, 3, in Fig. 2,and Fig. 4 is a horizontal section on line 4, in Fig. l.

The device embodies a casing l0, in the top 11 of which, and in thebracket l2, is pivotally arranged the end 13 of a shackle 14. Theshackle can be slid from the casing, as shown in Fig. 1 in dottedoutline, and is then free to be swung around, it beingrotatably'arranged in the casing. The shackle has a normal tendency toemerge from the casing through the action of a spring I5 bearing on apin 16, in the portion I3 of the shackle. The other end of the spring 15bears on the casing.

To normally hold the shackle shut,'or in its locked position, is a leverI7 pivoted at I8, and having a nose 19 to enter a slot 20 in thepportion13, the nose on the lever being -orced over by the action of a spring 2lbearing on a stud 22. The end 23 of the lever 17 projects downward inclose proximity to-a pin 24 for-the reception of a key, the relationbeing more specically 'brought out hereafter.

When the shackle has been slid into the casing, as in Fig. l, it islocked by the action of the spring 21 forcing the nose 19 into the slot20. However, the lock can be securely locked by a key manipulation ofsome of the parts, this being done by a key 25, shown in dotted outlinein Figs. 2 and 3. This key bears on a block 26 which is slid over by theaction of the key, and has the stud 27 enter a perforation 28 in the'end 29 of the shackle 14, the block being guided by the pin 27 passingthrough the bearing plate 28a and also by the rod 29 sliding in thefprked support 30. This forcing of the block is done against the actionoi a spring 3l which bears against the block, being held againstdisplacement by a pin 32, and the block having a flat plate 33 attachedthereto which has a notch 34. When the block has passed over to thepoint shown in Fig. 2, and where the key 25 will now just clear it, theblock is locked by i the finger 35 arranged to slide in suitablebearings, and being actuated by the spring 36 to force it up into thenotch 34. The finger 35 has a lug 37 thereon. The key 25, after the lockis locked? can be swung around without any hindrance when normallyoperated. This is Idue to the fact that the key has cleared the bottomof i the block 2G, and the lug 37 and the end. 23 of the lever I7 areout of th'e plane of rotation of the key. The key revolves on a key-pin24 which is narrowed down on its inner portion' to form a shoulder or astop piece for the washer 38,V which is held tight by the action of aspring 39. To release the lock, the kein-operated locked portion must beunlocked by means oi the key, and the key 25 is forced in against theaction of the spring 39 until it is within the plane of the lug 37,which will be apparent from Figs. 3 and 4. When the key is pushed in therequired distance, it follows the path as indicated at a in Fig. 2, andwhen the lug 37 is drced downward by the key, it causes the pin 35 torelease the plate 33 of the block 26, and the spring 3l operates tothrow the block 26 to cause the pin 27 to be withdrawn from the end 29of the shackle 14. The parts then assume the position showgirl Fig. l,and the key cannot be thrown back in `the reversed direction on accountof the lower end of the block 26 being in its path o travel.' The key isthus continued in the direction of the arrowva, and when the key istwisted aroundto be on the leit side, as we look at the drawing, of theend A23 of the lever 17, it is forced in against the action or' thespring 39 much further than it was necessary to force it for theoperation enters the casing. A guard 40 can be placed inside the casingadjacent to washer 38 so that the key, when it vey theoimpression thatit cannot be further forced into the casing. The cfuard lllis arrangedto partly snr-- round the pin 24, and it causes the rotation of the key25 in but one planefor a part of its rotation. The spring 39 is stiffsothat any accidental longitudinal movement o the key is avoided, andthere is no suggestion of a yielding pressure to an ordinary user ot`the key.

It will be seen, from this description, that the key operates in threeplanes, first to lock the key-operated portion of the device by engagingthe block 26, and must then beforced in first along its pin to engagethe lug 27, and must he released to clear the guard 40 and then forcingin still further to engage the end 23 of' the lever to unlock the springactuated locking portion.
